Technical Field

[0001] This utility model relates to a liquid pushing device. Background Technology

[0002] Currently, the incidence of anorectal diseases is very high, requiring surgical treatment of the affected area or rectal administration of medication or fluids to achieve better therapeutic effects. Rectal administration or fluids refers to delivering medication into the rectum through the anus. Typically, a squeeze-type liquid reservoir with an infusion head is used to store the medication. When using this method, the user holds the reservoir, inserts the infusion head into the anus, and manually squeezes the reservoir to deliver the medication into the rectum.

[0003] However, this method has the problem of easily getting the user's hands dirty when manually squeezing the liquid. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defect of existing technology in which the user's hands are easily soiled during the manual squeezing of liquid storage, and to provide a liquid pushing device.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A liquid-pushing device, characterized in that it comprises:

[0007] The housing has a receiving cavity;

[0008] A liquid storage assembly includes a liquid storage body, a conduit, and a dispensing head connected in sequence. The liquid storage body is located at the upper part of the accommodating cavity along the height direction of the accommodating cavity, and the liquid storage body is compressible. One end of the conduit is connected to the liquid storage body, and the other end is connected to the dispensing head.

[0009] A liquid-pushing assembly is disposed at the lower part of the accommodating cavity along the height direction. The liquid-pushing assembly includes a driving part and a liquid-pushing part. Under the action of the driving part, the liquid-pushing part moves toward the liquid storage body to squeeze the liquid storage body.

[0010] In this technical solution, by setting the overall structure of the liquid pushing device, the liquid is squeezed into the rectum by the liquid pushing component at a certain distance from the liquid dispensing head, which effectively avoids soiling the user's hands and maintains overall cleanliness.

[0011] Preferably, the liquid storage assembly further includes a holding member, which is sleeved at the connection between the conduit and the liquid dispensing head.

[0012] In this technical solution, by setting up a gripping component, an effective gripping position can be provided for the user when picking up the liquid dispensing head.

[0013] Preferably, in a predetermined direction from the liquid dispensing head to the conduit, the holding member includes a connecting blocking portion and a holding portion, wherein the outer diameter of the blocking portion is larger than the outer diameter of the holding portion.

[0014] In this technical solution, by setting up a blocking part, on the one hand, it can prevent the liquid dispensing head from entering the human body too deeply, and on the other hand, it can prevent the liquid flowing from the dispensing head from flowing to the handle and soiling the user's hands. By setting up a handle, it is convenient for the user to hold the dispensing head by hand.

[0015] Preferably, the outer diameter of the blocking portion gradually increases along the preset direction; and / or,

[0016] The gripping part is provided with multiple protrusions along the preset direction, and the multiple protrusions are spaced apart along the circumference of the gripping part.

[0017] In this technical solution, the outer diameter of the blocking part gradually increases along a preset direction to provide effective blocking. Multiple protrusions are provided on the gripping part along the preset direction, and these protrusions are spaced apart circumferentially on the gripping part to create greater friction at the gripping position, thereby making gripping more convenient and stable.

[0018] Preferably, the drive unit includes an electric cylinder, the electric cylinder includes a retractable free end, and the liquid pushing unit is disposed at the free end of the electric cylinder;

[0019] The liquid pushing device also includes a first support frame, which is used to support the electric cylinder.

[0020] In this technical solution, the above-described configuration provides a specific structure for the drive unit. Furthermore, by providing a first support frame, support can be provided for the electric cylinder, thereby preventing swaying when the free end of the electric cylinder extends.

[0021] Preferably, the drive unit includes: a motor and a first transmission component and a second transmission component that cooperate with each other;

[0022] One end of the first transmission component is sleeved on the outside of the motor shaft, and the second transmission component is sleeved on the other end of the first transmission component. The outer wall of the first transmission component and the inner wall of the second transmission component are provided with mutually cooperating threaded tracks.

[0023] The liquid-pushing part is located at the end of the second transmission component away from the motor.

[0024] In this technical solution, the above-described configuration provides a specific structure for a drive unit.

[0025] Preferably, the liquid pushing device further includes a second support frame, the second support frame including a first support portion and a second support portion arranged along the height direction, and an intermediate support portion arranged radially along the accommodating cavity. Along the radial direction of the accommodating cavity, one end of the first support portion is connected to the motor, and the other end extends away from the motor. One end of the second support portion is connected to the second transmission component, and the other end extends away from the motor. Both the first support portion and the second support portion are connected to the intermediate support portion.

[0026] In this technical solution, by setting a second support frame, the motor and the second transmission component can be effectively supported and limited.

[0027] Preferably, the end of the liquid dispensing head furthest from the conduit is the end portion;

[0028] From the infusion head to the conduit, in a predetermined direction, the outer diameter of the end gradually increases and then gradually decreases; and / or,

[0029] The liquid storage assembly further includes a protective cover, which is disposed over the end; and / or

[0030] The outer wall of the liquid dispensing head is marked with graduations.

[0031] In this technical solution, by setting a preset direction from the infusion head to the catheter, the outer diameter of the end gradually increases and then gradually decreases, thereby forming a barrier at the maximum outer diameter of the end to prevent the end from easily detaching from the body. The protective cover serves two purposes: protecting the end and preventing the medication from flowing out. The graduations on the outer wall of the infusion head allow for easy identification of its length and provide a reference for adjusting the position of the handle, preventing the end of the infusion head from entering the body too shallowly or too deeply.

[0032] Preferably, the liquid storage assembly further includes a connector, the two ends of which are respectively connected to the conduit and the liquid storage body;

[0033] One end of the liquid storage body is provided with a connector, the outer wall of the connector is provided with an external thread, and the inner wall of the connector is provided with an internal thread that mates with the external thread.

[0034] The liquid storage body, the connector, and the conduit are connected in sequence.

[0035] In this technical solution, by setting up connectors and the matching method between the connectors and the liquid storage body, the disassembly and installation of the liquid storage body and the conduit are facilitated.

[0036] Preferably, the housing has an opening corresponding to the position of the liquid storage body, the opening communicating with the receiving cavity, and the opening allowing the liquid storage body to pass through, so as to be placed into or removed from the receiving cavity; and / or,

[0037] The inner wall of the accommodating cavity is provided with a limiting part, which extends radially toward the center of the accommodating cavity and is used to restrict the liquid storage body from moving downward along the height direction.

[0038] In this technical solution, an opening is provided for the liquid storage body to pass through, facilitating its installation and disassembly. A limiting part is provided on the inner wall of the accommodating cavity to effectively limit the liquid storage body.

[0039] The positive and progressive effects of this utility model are as follows:

[0040] This invention, through the overall structure of the liquid-pushing device, allows the liquid to be squeezed into the rectum by the liquid-pushing component at a certain distance from the liquid dispensing head, effectively avoiding soiling the user's hands and maintaining overall cleanliness.

[0090] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0091] Example 1

[0092] like Figures 1-4 As shown, this embodiment provides a liquid pushing device 1, which includes: a housing 10, a liquid storage component 20 and a liquid pushing component 30.

[0093] The housing 10 is provided with a receiving cavity 11.

[0094] The liquid storage assembly 20 includes a liquid storage body 21, a conduit 22 and a liquid dispensing head 23 connected in sequence. The liquid storage body 21 is located at the upper part of the accommodating cavity 11 along the height direction H of the accommodating cavity 11, and the liquid storage body 21 is compressible. One end of the conduit 22 is connected to the liquid storage body 21, and the other end is connected to the liquid dispensing head 23.

[0095] The liquid pushing assembly 30 is disposed at the lower part of the accommodating cavity 11 along the height direction H. The liquid pushing assembly 30 includes a driving part 31 and a liquid pushing part 32. Under the action of the driving part 31, the liquid pushing part 32 moves closer to the liquid storage body 21 to squeeze the liquid storage body 21.

[0096] In this way, by setting the overall structure of the liquid pushing device 1, the liquid is squeezed into the rectum by the liquid pushing component 30 at a certain distance from the liquid dispensing head 23, effectively avoiding soiling the user's hands and maintaining overall cleanliness.

[0097] It should be noted that the outer wall of the liquid storage body 21 is provided with tooth-shaped folds along the height direction H, so that the outer wall of the liquid storage body 21 can be folded along the height direction H under the pressure of the liquid pushing part 32, thereby effectively squeezing out the liquid in the liquid storage body 21.

[0098] Preferably, the liquid storage assembly 20 also includes a gripping member 24, which is fitted onto the connection between the conduit 22 and the dispensing head 23. Thus, by providing the gripping member 24, an effective gripping position can be provided for the user when picking up the dispensing head 23.

[0099] Specifically, in the preset direction Q from the dispensing head 23 to the conduit 22, the holding member 24 includes a connecting blocking part 241 and a holding part 242, with the outer diameter of the blocking part 241 being larger than the outer diameter of the holding part 242. Thus, by providing the blocking part 241, on the one hand, it can prevent the dispensing head 23 from entering the body too deeply; on the other hand, it can prevent the liquid flowing from the dispensing head 23 from flowing to the holding part 242 and soiling the user's hands. By providing the holding part 242, it is convenient for the user to hold the dispensing head 23 by hand.

[0100] Preferably, the outer diameter of the blocking portion 241 gradually increases along a predetermined direction Q. In this way, by setting the outer diameter of the blocking portion 241 to gradually increase along the predetermined direction Q, effective blocking can be provided.

[0101] The gripping part 242 is provided with multiple protrusions 2421 along a preset direction Q, and the multiple protrusions 2421 are spaced apart circumferentially along the gripping part 242. In this way, by providing multiple protrusions 2421 along the preset direction Q and spaced apart circumferentially along the gripping part 242, greater friction is generated at the gripping position, thereby making it more convenient and stable to grip.

[0102] In this embodiment, the drive unit 31 includes an electric cylinder 311, which has a retractable free end 3111, and the liquid-pushing part 32 is disposed at the free end 3111 of the electric cylinder 311. However, it is not limited to this; in other embodiments, the drive unit 31 may be other components or structures that can push or drive the liquid-pushing part 32 to move. In this embodiment, the free end 3111 of the electric cylinder 311 and the liquid-pushing part 32 are fixedly connected by a fastener. The outer diameter of the free end 3111 is smaller than the outer diameter of the liquid-pushing part 32.

[0103] The side of the liquid pushing part 32 facing the liquid storage body 21 is a plane, which can effectively squeeze the liquid storage body 21.

[0104] The liquid pushing device 1 also includes a first support frame 50, which supports the electric cylinder 311. In this way, by providing the first support frame 50, the electric cylinder 311 can be supported, thereby preventing wobbling when the free end 3111 of the electric cylinder 311 extends.

[0105] Preferably, the end of the infusion head 23 furthest from the conduit 22 is the end portion 231; the outer diameter of the end portion 231 gradually increases and then gradually decreases along a predetermined direction Q from the infusion head 23 to the conduit 22. In this way, by setting the outer diameter of the end portion 231 to gradually increase and then gradually decrease along the predetermined direction Q from the infusion head 23 to the conduit 22, a barrier is formed at the maximum outer diameter of the end portion 231, preventing the end portion 231 from easily detaching from the human body.

[0106] The inner diameter r1 of the end 231 of the dispensing head 23 is 0.5mm-1.5mm. By setting the range of the inner diameter of the end 231 of the dispensing head 23, the inner diameter of the end 231 of the dispensing head 23 is made smaller, thereby increasing the force of the liquid flowing out from the end 231.

[0107] The inner diameter r2 of catheter 22 is 1mm-2mm. By setting the range of the inner diameter r2 of catheter 22, a corresponding liquid delivery rate is maintained. On the one hand, this avoids the rate being too fast, which would result in excessive force; on the other hand, it avoids the rate being too slow, which would fail to provide the appropriate force.

[0108] The wall thickness of conduit 22 is 0.8-1.2 mm. By setting the range of wall thickness values ​​for conduit 22, the structural strength of conduit 22 can be maintained while balancing cost control.

[0109] The length of the catheter 22 is 30mm-60mm. By setting the range of the length of the catheter 22, we can avoid the catheter being too short, which would be inconvenient for the user to operate, and on the other hand, we can avoid the catheter being too long, which would lead to excessive manufacturing costs.

[0110] The liquid storage assembly 20 also includes a protective cover 25, which is installed over the end 231. By providing the protective cover 25, the end 231 is protected on the one hand, and the liquid is prevented from flowing out on the other hand.

[0111] The outer wall of the dispensing head 23 is provided with a scale 232. By providing the scale 232 on the outer wall of the dispensing head 23, the length position of the dispensing head 23 can be known, and a reference can be provided for adjusting the position of the holding member 24, preventing the end 231 of the dispensing head 23 from entering the human body too shallowly or too deeply. The holding member 24 can move on the outer surface of the dispensing head 23, moving to the corresponding position according to the scale 232.

[0112] Preferably, the liquid storage assembly 20 further includes a connector 26, with both ends of the connector 26 connected to the conduit 22 and the liquid storage body 21, respectively. One end of the liquid storage body 21 is provided with a connector 211, the outer wall of which has an external thread, and the inner wall of the connector 26 has an internal thread that mates with the external thread. The liquid storage body 21, connector 26, and conduit 22 are sequentially connected. Thus, by providing the connector 26 and the way the connector 211 of the connector 26 and the liquid storage body 21 are connected, the disassembly and installation of the liquid storage body 21 and the conduit 22 are facilitated. The conduit 22 is inserted at the end of the connector 26 furthest from the liquid storage body 21.

[0113] In this embodiment, the housing 10 has an opening 12 corresponding to the position of the liquid storage body 21. The opening 12 communicates with the receiving cavity 11 and allows the liquid storage body 21 to pass through, so as to be placed into or removed from the receiving cavity 11. Thus, by providing the opening 12 for the liquid storage body 21 to pass through, the installation and disassembly of the liquid storage body 21 are facilitated. Furthermore, one end of the opening 12 is provided with a fixing groove 13, and the connector 211 is disposed in the fixing groove 13.

[0114] A limiting portion 14 is provided on the inner wall of the receiving cavity 11. The limiting portion 14 extends radially toward the center of the receiving cavity 11 and is used to restrict the downward movement of the liquid storage body 21 along the height direction H. Thus, by providing the limiting portion 14 on the inner wall of the receiving cavity 11, the liquid storage body 21 is effectively limited. For the specific location and structure of the limiting portion 14, please refer to [link to relevant documentation]. Figure 8 .

[0115] Example 2

[0116] like Figures 5-8 As shown, the overall structure of the liquid pushing device 1 in this embodiment is basically the same as that in embodiment 1. The difference is that the composition of the driving part 31 in this embodiment is slightly different from that in embodiment 1.

[0117] Specifically, the drive unit 31 in this embodiment includes a motor 312 and a first transmission component 313 and a second transmission component 314 that cooperate with each other.

[0118] One end of the first transmission component 313 is sleeved on the outside of the rotating shaft 3121 of the motor 312, and the second transmission component 314 is sleeved on the other end of the first transmission component 313. The outer wall of the first transmission component 313 and the inner wall of the second transmission component 314 are provided with mutually cooperating threaded tracks.

[0119] The liquid-pushing part 32 is located at the end of the second transmission component 314 away from the motor 312. In this embodiment, the liquid-pushing part 32 and the second transmission component 314 are integrally formed, thereby making the structure more robust.

[0120] Preferably, the liquid pushing device 1 further includes a second support frame 60, which includes a first support portion 61 and a second support portion 62 arranged along the height direction H, and an intermediate support portion 63 arranged radially along the accommodating cavity 11, the intermediate support portion 63 being located between the first support portion 61 and the second support portion 62. Along the radial direction of the accommodating cavity 11, one end of the first support portion 61 is connected to the motor 312, and the other end extends away from the motor 312; one end of the second support portion 62 is connected to the second transmission component 314, and the other end extends away from the motor 312; and both the first support portion 61 and the second support portion 62 are connected to the intermediate support portion 63. Thus, by providing the second support frame 60, the motor 312 and the second transmission component 314 can be effectively supported and limited.

[0121] In this embodiment, the outer wall of the housing is also provided with a button 70 that is electrically connected to the motor 312 to control the forward and reverse rotation of the shaft 3121 of the motor 312, thereby controlling the liquid pushing part 32 to squeeze the liquid storage body 21 or move in the opposite direction.
